a few bath time questions
Mr Whippy - 19/3/08 at 08:46 AM

Ok so the electrolyse bath is working full time now doing stirling work on all my rusty bits but I have a few questions -

1) Bits with chrome on them (both in rusty bit and the clamp I'm using to connect neg terminal - is this not a good idea, does the chromium go into the water? am I about to get poisoned???

2) galvanised parts, what’s happening to the zinc, is that going into the water?

3) can I coat stuff in zinc some how using this setup, assuming I wear protection?

4) What’s a safe voltage before I kill myself, 24v still safe?

Try it. If we don't see any posts next week then the answer is yes.

I'd like to think you are not doing this in the kitchen but a well ventilated place. and providing you don't use the water to make tea, you should be fine.























probably.

I use an 18v laptop PSU which has been fine.

Im lucky the garage is draughty so the same howling gale that fills the place up with leaves every 24 hours takes away any fumes.

The baths outside next to the garage, it was to big to put inside and doesn't really matter if it gets wet

Not sure what the fumes are, I assumed it was CO2, sure are a lot of bubbles. I don't have a spare PSU I was thinking of using a 24v battery charger for diggers etc

The waters looking real nasty now just checking that it’s not poisonous as well.

hmm I see a silverline charger with this spec -

Charging output 12/24v. Min AH rating 20AH, max AH rating 100AH. Thermal overload protection, easy to read ammeter polarity inversion and fast charger. Complete with carry handle and jump leads.

- 20amps thats quite a lot? my charger is about 3amps I think.

Not sure its safe for charging the bath water, anyone know?

There was someone on here I think using an arc welder to supply the amps in a big bath derusting a chassis

holy crap thats mad

The gas given off is mostly Hydrogen and Oxygen i.e. rocket fuel. That's why you don't want it building up in a confined space as it's extremely explosive. Depending on impurities in the water and metal other poisonous gases may also be given off.

I assume it's Hydrogen Bubbles, because your sposed to let them leech out of the metal after it's been bubbling for a few hours/days!!!

I get this general level of bubblage (with an old CB Radio PSU that went bang)

Wasn't the chromium content of stainless the reason stainless electrodes aren't recommended on the electrolysis thread? I have a feeling it leads to some pretty nasty things in your electrolyte!

Hydrogen! oops (sitting next to the bath is the lighter and blowtorch whippy was using to burn the paint off...)
